I am planning to write a book in my mother tongue (so excuse my bad grammar). It's in "Business and Management"
So, while I was reading books for my references, I found a well organized book. I took the index, the titles like (Microeconomics, Macroeconomics, Marketing...etc) and followed the structure of chapters, titles and subtitles from that book. However, I used my thoughts and own professional language to explain each title, and added extra examples and quotes from other writers....
Kindly note that all the Chapters and titles are common scientific phrases that do not belong to the author.
And What is OK to quote? Sometimes I quote a definition or a paragraph, and of course I'll refer it to the original author and book...
Is that legal or illegal?
